Heisenberg Indeterminacy Equation

In the sixth edition solution manual, the solution for problem 1.43 uses the equation (deltap) * (deltax) = 1/2*h. Is the same as the (deltap) * (deltax) = h/4(3.14) equation that we were given in class?

Re: Heisenberg Indeterminacy Equation

The equation from the book that you’re referencing uses the constant “h bar”(the typical h but with a line trough the stem of it) h bar is equal to h/2(pi). So when you substitute this you get the familiar h/4(pi).
